Ok I know that I am going to get slack for what I say here.
Hell some may say that I'm not truly a sub.. Well guess what I know I am so I really don't care what is said.
Here is what I have learned for myself in the short time that I have been on my journey. It may not be for everyone but as I have seen from reading blogs sometimes my lessons on my journey and my insights for me maybe resonate for another..
Sometimes a Dom enters our journey on finding our long-term one as a stepping stone. Not only for the sub but also for the Dom. There is an aspect of both that each of them needs at that moment. Sometimes to open the door to the lifestyle, sometimes to introduce a kink or taking to another level.
Sometimes that feeling of " Love " is not for the person but the stepping stone and what was opened and exposed.
Yes you will always care for that person and appreciate what was exposed, but the "love" was not for them.
Once that is realized that is when you are truly free and ready to take the next step..
Hopefully that helps someone.
